To @ZZ whom it may concern.-

Be it known that I, JOHN M. SINOLAIR, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented a new and usefullmprovement in Grate-Bars, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in grate bars, and consists of a grate bar formed of two longitudinal sections and a removable top section, the latter having depending pins or side pieces embracing parts of the said longitudinal sections.

It further consists of the combination of parts hereinafter set forth and claimed.

bar embodying my invention. Fig. II repre-l sents a vertical cross section thereof. Fig. III represents a side view of a modification thereof. Fig. IV represents a vertical cross section of the bar shown in Fig. III. Fig V represents a vertical section of another modication of my invention.

Similar letters of reference indicate corresponding parts in the several igures. l

Referring to the drawings: A designates each of two side sections of the body of a grate bar, and B a top section upon said body, the said body sections being divided in the longitudinal plane of the bar. On the top section B are formed the teeth O,which ox` tend across the bar, and usually project laterally therefrom as shown. Said top section B is detachably united to the body A, so that it may be entirely separated and removed therefrom, and hence the teeth C are rendered independent of the body, permitting their renewal at pleasure. 4

Various means may be employed for uniting the top section B to the body A, and in the body A, both on the sides and onvthe under portions thereof.

In Figs. I to IV, inclusive, the side sections are shown as forming a hollow body, open at both ends as o andalso open at the bottom, intermediate of the ends thereof, as at s, and by this arrangement of openings a circulation of air is provided in both a longitudinal and vertical direction through the bar for cooling it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A grate bar consisting of longitudinal side sections and a top section provided with pins or cheek pieces embracing and securing said side sections, said parts being combined substantially as described.

2. A grate bar consisting'of side sections forming a hollow body, and a removable top JOHN M. SINCLAIR.
